UNITED STATES PATENT OFFICE.

HUBERT VINCENT BLAKE, OF ACORINGTON, ENGLAND.

HYDRAULIC RAM.

SPECIFICATION forming part of Letters Patent No. 668,672, dated February26, 1901.

Application filed January 2, 1901.

To all whom it may concern:

Beit known that LHUBERTVINOENT BLAKE, a subject of the Queen of GreatBritain, residing at Oxford street, Accrington, in the county ofLancaster, England, have invented certain new and useful Improvements inHydraulic Rams, of which the following is a specification.

My invention relates to improvements in hydraulic rams; and the objectof myinvention is to obtain greater efficiency by an improvedconstruction of waste or pulse valve.

In order that my invention may be fully understood and readily carriedinto effect, I will describe the accompanying two sheets of drawings,reference being had to the letters marked thereon.

Figure l is a side view of a hydraulic ram fitted with my improved wasteor pulse valve. Fig. 2 is a side elevation, on a large scale, of thebody of the improved waste-valve and its cover, one-half being shown insection. Fig. 3 is a plan view of Fig. 2, showing also a rubber band inposition; and Fig. 4 is an elevation of the rubber bands mounted uponrods secured upon the cover of the wastevalve.

In the drawings, a designates the body of the ram; 1), the pipe throughwhich the water enters the ram; 0, the casing of the waste or pulsevalve; d, the air-vessel, and f the'discharge-pipe for the water raisedby the ram. As my present improvement only relates to the waste or pulsevalve the other parts of the ram may be of any other desiredconstruction and are not shown in detail.

The improved waste or pulse valve consists of a hollow vessel 0,preferably circular in cross-section and bolted to the body of the ramin the position shown in Fig. l or in any other desired position. Thisvessel is perforated with one, two, or more belts or groups of holesopposite to which on the inside of the vessel are a corresponding numberof india-rubber or other suitable elastic bands Serialllo. 41,764.(NomodeL) h, mounted upon a frame 1', secured to and carried by a flangej, which when the frame '1; is inserted in the vessel cforms a' coverfor the latter, to which it is securely bolted to withstand the pressureof water.

In operation water flows from the pipe 1) into the body of the ram 0.and valve-casing c, and a portion escapes under the elastic bandshthrough the perforations in the easing until the pressure of waterexpands the bands and closes the perforations, thus forcing water upwardinto theair vessel (1 and away through the delivery-pipe f at eachstroke of the ram.

I have shown in the drawings the interior of the vessel ccircular insection; but I wish it to be understood that it might be of any otherform, if desired,and also in place of stretching the india-rubber bandsIt over a frame with five rods the frame might have three, four, or morerods, and, further, the frame may be separate from the cover.

One advantage of placing the india-rubber bands inside the hollow vessel0 to form the waste or pulse valve is that the bands hcan be moreconveniently examined and renewed and, further, that the size and weightof the body of the ram may be greatly reduced.

What I claim as my invention, and desire to secure by Letters Patent ofthe United States, is-

In a hydraulic ram, the improved waste or pulse valve consisting of ahollow vesselprovided with one, two or more belts or groups of holes incombination with an india-rubber or other suitable elastic band or bandsmounted upon a frame and placed in the interior of the hollow vessel,substantially as and for the purposes described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

HUBERT VINCENT BLAKE.
